Review on LQ Industrial 12PCS Black Solid Brass Sam Browne Button Screw Studs Nail Round Rivets - Perfect for DIY Leather Craft Belt Wallet Handbag - Size: 5x7x7mm by Denise Davis

One of the ends of the 'nut' (bolt) was damaged - looks like it was partially cast in the die. The two ends of the "bolt" (back side) are fused together head to head (I don't know how that happened unless it was the result of a manufacturing error). 28 out of 30 isn't that bad, but it's still over a six percent failure and I paid for 30. Revain doesn't do partial refunds and I needed ten of these so I'll have to unnecessarily reorder at some point. It's not a terrible rejection like some of them (I've seen rejection rates as high as 15%), but it's still pretty embarrassing that it's being sold that way.
